2d
a triangle is 2D whereas a triangular prism is 3D.
2-Dimensional
Pentagon 2d shape is a pentagon 3d object is a pyramid.
A square.It is a square
1d has only the length, but 2d has both the length and width.
1D a single line (?) 2D a flat shape 3D a cube
1D has vertical bars that are read horizontally, 2D has small squares that are read simultaneously both horizontally and vertically. 2D barcodes can store much more information than 1D barcodes can.
It doesn't have any volume (3D) and it's not a line (1D). Thus, it is a 2D shape.
1d array contains single row and multiple columns and 2d array contains multiple row and multiple columns. 2d array is a collection of 1d array placed one below another,while 1d array is simple a collection of elements.
None
There's no difference. They're the same thing.
2d+1d= 3d
only heard about 2d and 3d, 2d is the traditional two-dimensional animation on paper scanned into a computer, Flash software, making paperless animation, it's a two-dimensional space
it is 1D signal.

1D diesel fuel has lower viscosity and a lower pour point than 2D, so is preferred for cold weather. 1D diesel fuel has only about 95 percent of the energy output as 2D, causing reduced gas mileage and lower horsepower. 2D fuel is used in warmer weather, and also can be mixed with 1D for an effective winter fuel.
